Title: Metastasis-associated collagenolytic metalloproteinases.
Inventor: NAKAJIMA MOTOWA
IPC: C12N5/10
Filed: 1990-01-29
Abstract: Disclosed are methods and compositions for testing for various types of human cancers, including in particular metastatic mammary carcinoma, colon carcinoma astrocytoma, renal cell carcinoma, and teratocarcinoma malignant melanoma. The diagnostic method of the invention involves the detection of a gelatinolytic and type IV collagenolytic metalloproteinase having molecular weight of approximately 88 to 92 kilodaltons in size. This high molecular weight type IV collagenolytic enzyme is found to be associated with the cancerous state, but this has not been found in any noncancerous cells tested and further not found in the serum of non tumor bearing animals. The enzyme is associated both with rat and human tumors, the enzyme in each case being quite similar. Methods are disclosed for isolating the 88/92 kd enzyme, the isolated enzyme being useful as a control enzyme and diagnostic assays. Furthermore, the isolated enzyme will be useful in the preparation of antibodies, including monoclonal antibodies, having specificity for the metastasis-associated enzyme. Techniques are also disclosed for isolation and partial purification of the enzyme from both rat and human sources. Furthermore, methods are disclosed for conducting both enzymatic and immunologic based tests for the diagnosis of metastatic and recurrent disease.

Abstract: A power-on clutch-to-clutch downshift control is initiated by partially releasing an off-going torque transmitting device (C1,C2,C4) to permit an increase in the transmission input speed. At the same time, an on-coming torque transmitting device (C1,B1) is filled in preparation for engagement. When the slip across the on-coming device is near zero, the on-coming device pressure is progressively increased while the off-going clutch pressure is controlled to maintain the near-zero on-coming slip speed condition. When the on-coming device develops significant capacity, a tie-up develops between the on-coming and off-going devices, causing a drop in output shaft (30) acceleration. The drop is detected and used to release the off-going device, the shift being complete when the on-coming device is fully engaged. Engine (12) torque controls are employed to ensure a smooth output torque transition at the end of the shift.

Abstract: An optical disk drive apparatus is provided which has a gain controller for controlling the gain of the servo loop of the focusing means so as to keep the laser beam spot focused on the optical disk in response to the seek velocity of an optical head. At a low seek velocity, the focus servo gain is reduced in order to reduce or eliminate the influence that beam scattering on the groove of an optical disk would otherwise have on a focusing error signal (FES) and a tracking error signal (TES). At high seek velocity beam scattering does not affect the FES or TES and hence the focus servo gain is held at its normal track following value.
